Pump.fun Integrates HyperEVM, Unlocking Zero-Fee Trading

Pump.fun has made significant strides in its evolution as a multi-chain platform by fully integrating HyperEVM into its mobile app. This move makes it the first app to offer complete support for Hyperliquid's EVM-compatible execution layer, allowing users to trade HyperEVM tokens against USDC with near-zero fees.

HypervEM is the smart contract layer of the Hyperliquid L1 blockchain, operating under chain ID 999. It runs alongside HyperCore, which handles the exchange's core order book operations, while HyperEVM opens the door to general-purpose smart contracts and ERC-20 tokens.

The integration follows a phased approach, with partial support introduced weeks prior to the full rollout. This allowed the team to stress-test the infrastructure and iron out edge cases.

For active traders, the integration removes friction when accessing HyperEVM tokens, particularly for high-frequency, small-size trades characteristic of meme token markets. However, there are risks worth noting, including potential gas fee spikes as adoption grows.
